BACKGROUND

Two Dellner Brakes type SKP 4x120-68 spring applied, hydraulically released disc brakes are installed on the luffing and trolley travel hoists of two ship loaders for bagged material.

SUMMARY

The brakes operate on 2090 mm (82.3 in) diameter discs that are mounted on each hoist drum for holding and emergency stopping. (Total of 8 brakes on 4 discs). Brake torque per disc is 199,5 kNm (1,760,00 lbf-in) with 95 bar (1,380 psi) releasing pressure.

Also each loader has two SKP 50 spring applied, hydraulically released service brakes with mounting stands installed between the hoist motors and reduction gears. Because the loaders operate near the sea, the brakes were manufactured with extra corrosion protection.
